Explanation:
North America is a continent entirely within the Northern Hemisphere and almost all within the Western Hemisphere. In can also be described as a northern subcontinent of the Americas[5][6] in models that use fewer than seven continents. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the west and south by the Pacific Ocean, and to the southeast by South America and the Caribbean Sea.North America covers an area of about 24,709,000 square kilometers (9,540,000 square miles), about 16.5% of the earth's land area and about 4.8% of its total surface.
1. <span>tRNA is the one carrying amino acids

3. </span><span>The type of chromosomal mutation that occurs here is an example of a deletion mutation. Specific genetic data, or DNA is removed and the remaining portions of chromosomal information have rejoined.

5. </span>The mutagens that result in cancer damage DNA by (b) weakening the DNA strand or interfering with base pairing. This mutagens are called carcinogens, if they cause a damage to a gene that makes a DNA repair protein, it means that a cell will have less ability to repair itself, and ,as a result, this will lead to formation of cancer.

Already a few months prior after being buried, the body is already decaying. The body builds up with gas and has nowhere to go so the body becomes bloated thus attracting insects that break down the body and eat away as it progresses through the decaying process. The body goes through 5 stages of decay and thats autolysis and putrefaction. Autolysis, the body's enzymes begin to go into a meltdown and its sped up by extreme heat and slowed by extreme cold. Putrefaction is the bacteria that escapes from the body's intestinal tract and actually begins the process of literally melting the body down. Black purification is when the skin turns black and the corpse collapses and the gasses escapes. Fermentation is when the strong odors develop and there will be surface mold but the body has begun to dry out. Dry decay is when the cadaver has mostly dried out and the decaying process has slowed considerably. This when it starts taking longer but all the nasty stuff is over. So after twelve years and all that happens within the first years of being dead with or without a coffin at that. But in the end the body will be fully decomposed in 8-12 years and all that is left are the bones.
